Load and fragment identifier(#id)

As per the load section

10.1.8 The load Element
   This action traverses the specified link
   
  Linking Attributes 
    Link to external resource to load ...


According to the above text a load pointing to a fragment identifier
within the current document is illegal ("link to external resource")

So this load would be illegal
  <load ev:event="xforms-activate" src="#id_in_the_current_document"/>


If loading to #id_fragment is legal, then what should be the behavior?

1. A new instance of the (current) document is loaded. Hence new state,
new instance data (initialization etc..)

2. Current document state/context is retained, but simply focus is set
to the target "id".

3. Finally, Is there a difference between the following 2 actions
   <load ev:event="xforms-activate" src="#id_in_the_same_document"/>
    vs.
   <load ev:event="xforms-activate"
src="current_uri#id_in_the_curent_document"/>
